The application discloses a three-dimensional posture corrector with wrist protection function, and belongs to the technical field of sitting posture correction. The three-dimensional posture corrector with wrist protection function comprises a writing board and a supporting piece. The writing board has an upwardly inclined writing surface. The supporting piece is arranged on the lower end surface of the writing board, the upper end surface of the supporting piece abuts against the writing board, and the lower end surface of the supporting piece is horizontally arranged. One end of the writing board is upwardly and obliquely extended, the other end of the writing board extends along a first direction and a second direction, and a transition surface is formed in the first direction and the second direction. The writing board comprises a supporting structure formed by the extension of the transition surface, and at least part of the lower end surface of the supporting structure is located on the same horizontal plane as the lower end surface of the supporting piece. The supporting structure is formed by the outward extension of the transition surface, and can be used for placing the wrist and / or the elbow, so as to improve the situation that the wrist or the elbow is suspended or pressed against the side edge of the writing board, improve the use comfort of the writing board, and improve the posture correction effect.
